I don't believe there's any better reason than wanting the small population states to sign the Constitution in the 1780s. And maybe also an attempt to protect the needs of people like farmers from being ignored, since they would live in low population states compared to urban professionals. Not saying it's a good idea.

It was definitely not created to protect the interests of farmers. The vast majority of the population worked in agriculture at that point, so they wouldn't have needed any special protection.
